Application filed June 2, 1925. Serial H0. 84,488.

The invention is a weather forecasting in v strument in which graphicrepresentations of a ship or other object or of conditions of theweather are automatically portrayed.

The object of the invention is to provide a weather forecastinginstrument which automatically portrays graphic representations of aship or other object, or different conditions of the weather.

Another object of the invention is to provide a means for attaching ananeroid barometer to a plurality of miniature pictures so that thepictures will be brought into different positions as the barometeroperates.

7 And a further object of the invention is to provide a means 'forprojecting miniature pictures in combination with an aneroid barometerfor moving the said pictures.

With these ends 1n view, the invention embodies an aneroid barometer, alurality of representations of a shi or the like in combinationtherewith and being arranged so that they will move in difierentpositlons as the barometer operates a projector for throwing the saidrepresentations on an enlar ed surface and a suitable casing for the.

sai barometer and rojector.

Other features and advantages of the invention will appear from thefollowin description, taken in connection with the rawin wherein igure 1is an exterior view of the casing.

Figure 2 is a view showing the arrangement of the aneroid barometer, theprojector and the screen.

Figure 3 is a view showing the gears for operating the discs having theminiature re resentations thereon.

igure 4 is a view showing an alternate means for operating the disc.

Figure 5 1s a diagrammatic view showing the means for operating thesoleonid.

In the drawings I have shown my device .as it would be made whereinnumeral 1 indicates an aneroid barometer, numeral 2, a disc upon whlchminiature plctures are placed and numeral 3 a projector.

The barometer 1 may be of any suitable edge and the wheel 7 and gear 6are mounted sails should be arranged for the different conditions ofweather or illustrating storms, winds or sunshine to portray thedifie'rent conditions of weather, and it will be observed that theseminiature ictures may be arranged in combination with the barometer sothat as any particular condition of the weather is approaching, thebarometer will move the miniature picture disclosing how the ship shouldbe arranged for this particular condition of the weather to the visibleposition.

A projector 3 may also 'be used in combination with the barometer toproject the miniature picture on the film upon a screen or lens as shownin Figures 1 and 2. This projector may be of any suitable type and maybe arranged in any suitable manner to project the picture as may bedesired.

The barometer, film disc and projector may be enclosed in a casing 11having a' screen 12 in its face as shown. The picture will be projectedupon the screen as shown and the de ees may also be projected on thelower e go of the screen as indicated by the numeral 13, as the de recsmay be placed on the film'helow the miniature pictures.

An alternate design'is shown in Figures 4 and 5 in which the disc 7 isoperated by a solenoid 14 throu h a rack 15 and a inion 16 that may be paced on the inner side of barometer will engage these contact points 1 0to complete circuits through the sections of the solenoid. The contactpoint .19 is connected by a wire 20 to each of the sections and the wire20 may be connected to a battery 21 or to any suitable source ofelectric current. It will be observed that the sections 17 may bearranged and connected in such a manner that as the different points areengaged by the lever 19, the rack 15 will move into or out of thesolenoid and thereby operate the disc 7 to display the picture that willportray a symbol indicating the condition of the weather.

It will be understood that changes may be made in the constructionwithout departing from the spirit of the invention. One of these changesmay be in the type of barometer used, another may be in the connectionbetween the barometer and the film disc, another may be in thearrangement or size of the film disc, another may be in the type ofprojector used or in the means for projecting the pictures and stillanother may be in the design or type of screen used or in the omissionof the screen and projector so that the pictures may be observed througha small opening.

Having thus fully described the invention, what I claim as new anddesire to secure by Letters Patent, is

1. In a weather forecast ng instrument, a continuous rotary film, saidfilm having graphic representations of an object or of difierentconditions of weather thereon, an aneroid barometer, suitable gearsconnecting the said barometer to the said film to cause the film torotate as the barometer operates, a lamp in combination with the saidfilm positioned to throw light through the said film, a screen adjacentthe said film upon 80 which the representations on the film may beprojected by the said lam and a suitable casing for enclosing the saidevice.

2. In a weather forecasting device, a film having graphicrepresentations thereon, 85 means for rotatably mounting the film in asuitable casing, means for automatically rotating the said film asconditions of the weathcrchange, and means within the said casing forprojecting the representations on 40 the film upon a surface in thefront of the said casing.

3. In a display device for forecasting conditions of weather, acontinuous film, means for rotatably supporting the said film, ananeroid barometer, suitable connections between the said barometer andfilm for automatically rotating the said film as the barometer operates,said film having a plurality of representations thereon, a suitable.casing for enclosing the said device, said casing having a translucentsurface at one side, and means for projecting the representations on thesaid film upon the said trans- 1 WALTER LEWIN.
